Application' ledAug'ustBl, 1923.` .Serial No.658,481.l i l To all wlw/mit may concern:

Be it known that I, Donsnr M. I/VIRTH,

a citizen of the United States,residing at` described in my co-pendingapplications' filed December 2, 1922 and July 17, 1923` and bearingSerial Numbers 604,457 and y 652,024, respectively. c

In carrying out this invention it is ymy purpose to provide a beltbuckle wherein an elastic tensioning means is provided between thebuckle andthe end of the belt attached thereto for allowing theexpansion and contraction of the belt while-in position upon the waistof the wearer for thereby preventing the usual necessity of theadjustment of the belt while in use.

With the above and other objects in view as the nature of the inventionis better un- Figure 2 is a bottom plan view thereof,` Figure 8 is abottom plan view` of ar slightly modied form of belt buckle,"and

Figure 4 is a bottom plan view of yan atv-- tachment that may beemployed in conjunction with the type of belt buckle shown in Figure 3.

Now having particular reference to the drawing, and first to Figures 1and 2, 5 indicates a belt buckle of'well known construction thatincludes the usual arcuateshaped top plate 5 formed upon opposite sideswith flanges 6 that are provided with alined inclined slots 7 throughwhich pro-k ject the pintles 8 upon the ends of a corrugated crossroller 9, the free end of the belt which is indicated by 10 adapted topass between this roller and the under side of said arcuate-shapedportion 5 whereby a pull upon the belt will naturally draw the rollerupwardly againstthe belt and consequently firmly ymaintain the sameconnected to thepbuckle as is obvious. i l

invention per seembodies the provi-` sion of,y a cross pin llthat issecured between said flanges 6 rearwardly ofthe-roller 9 and pivotallysecured to this cross pin is a wire bail member; 12 the 4free kends ofthelegs thereof being formed kwith eyes 13 for en? gagement uponlsaidcross pin. Bridging the legs ofthe bail member 12 isa pin 14 Ltheopposite ends thereof being eyed at` 15 for the reception of saidy legs,this cross pin 14 adapted to be engaged by the looped por-y tion 10 'ofthe before-mentioned belt 1() the opposite ysides of this loopedportionbeing notched as at 10 for permittingfof the properengageme'ntofthis looped portion,

withL the ybuckle Aasvinore clearly shown rin Figure 2.

Surrounding the baily 12 rearwardly of the cross pin 14is a lhelicalspring 16 that serves as a means for forcing the cross pin 14 inadirection forwardly for consequently applying tension to the belt 10.

In view of the above it `will at once/be apparent that I have provided ahighly novel and simplified form of tensioning means for belt bucklesand one that will answer 7all of the purposes above ascribed.'

Now having particular reference to Figure 8, 5 indicates the belt bucklethat 1s provided at its side edges with flanges 6 between which extendsa cross pin 8 that carries a locking, tongue 9 for the purpose oflocking the belt to the buckle when this tongue isr swung to theposition shown this construction being of a conventional design andtherefore clearly obvious to those Skilled invtheart. Pivotally securedto this cross pin 8 at opposite ends thereof are the front ends ofpendant anges 17 formed upon a plate 18 the front edge of this plateadapted to be engaged by rearwardly extending fingers 19 that are formedupon r otherwise suitably secured to said cross pin 8 whereby when thebelt is secured to the buckley in a manner hereinafter described andthesaine' positioned around the waist of the wearer the liability of thelocking tongue 9 from becoming displaced is sub.k stantially reducedthis particular construc tion being clearly set forth in` the last menntioned pending application set forth above.

In this instance the eyed ends 13 of the bail 12 are engagedthroughopenings in the rear ends of the above mentioned flanges 17 ofthe plate 18 and spanning the legs of this bail, rearwardly of the plate18, is a cross pin 14 the opposite ends thereof being eyed for thispurpose and these eyed ends being designated 15. Also surrounding thisbail rearwardly of this cross pin 14 is a helical spring 16 that answersthe same purpose as the spring 16 in the form of the invention shown inFigures l and 2.

l/Vith particular yreference to Figure 4L there is shown an attachmentfor a belt buckleof the type ldisclosed inFigureS and in this instancethe with guide iangesl to which aresecured at the rear ends thereof thehooked ends 2O of rearwardly directed pinsQl the opposite ends vof thesepins being joined by: a cross member22 and surrounding eachof 4the pinsbetween this cross member "and a cross pin Qfare expansion springs 24.The cross pin 23 is freely slidable upon said rearwardly directed pins21 and is normally forced forwardly by the action of said springs 2f itbeingobvious in this instance that the belt 10 is to be loopedaroundsaid cross pin 23 in a manner similar to the' belt shown in Figures 1and 2 the opposite edges late 18 is also formed' of this looped portionbeing also notched fory purposes previously set forth.

ln View of the above description it will at once be apparent that I haveprovided several novel forms of belt buckles the nature of the samebeingsuch as to answer all of the purposes ascribed and even though Ihave herein set forth the most practical embodiments of the inventionwith which I am at the present time familiar, itk is nevertheless to beunderstood that other modifications may be had without departing fromthe spirit and scope of the' appended claim.-

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is r A buckle structure comprising a bodyhaving means for engaging a strap7 a bar disposed transversely of thebody7 a bail having its ends pivotally connected with the bar,v

a bar slidably mounted upon the end portions of the bail, and a springcoiled about the outer portion of the bail andv having its ends bearingagainst the side of the bar which is slidably-mounted upon the bail.

In testimony whereof l aiiix my signature.
